The TLP267J(E) optoisolator is a triac, SCR output device used for isolating AC switching signals in a wide range of applications, from low-voltage domestic appliances up to high-power industrial equipment. It has an operating temperature range of −40 °C to +100 °C, and is suitable for operation in harsh environments.

The TLP267J(E) is a part of Toshiba\'s OPTO COUPLER (Optical Isolator) family which comprises devices with triac, SCR output and thyristor output configurations. The devices feature high electrical insulation and abnormal surge protection for safe operation. They are used in a wide range of application areas including consumer electronics, telecom, household appliances, automotive controllers, industrial control, lighting, and electric power.

The TLP267J(E) is a low-power optoisolator with a triac, SCR output, typically rated for 25 mA at 100 V. It consists of an infrared LED and a 3-terminal triac output driver. The device has an isolation voltage of 5000 VRMS (min), and its integral light-blocking optical filter prevents noise from each triac output. The device’s circular LED light emission prevent distortion which usually occurs with other 6-pin package –square emission type. The off-state isolation voltage of Van\'s is 6 kV , and the switching speed is 1000 to 1200 V/μs.

The TLP267J(E) comes in an industry-standard 6-pin DIP package which is compatible with existing industry standards. It also forms an integral part of Toshiba’s optocoupler family, allowing for easy management and power supply, allowing designers to easily include the device in any system.

The working principle of the TLP267J(E) is simple. The LED is illuminated by an input current which is provided by an external power circuit. This current is then converted into a proportionate increase in the light intensity of the LED, which in turn is detected by the output driver of the device, usually a MOSFET or a silicon controlled rectifier (SCR). The output signal is then used to operate AC switching circuits, such as triggering a thyristor or switching a triac.

The TLP267J(E) is easy to install and is designed for use in applications up to 100 V and 25 mA, making it an ideal choice for a wide range of AC switching circuits. It also offers a high breakdown voltage of 5000 VRMS (min), enabling safe and reliable operation in environments which have high temperature fluctuation or are prone to surges. The device is also characterized by low power consumption, fast switching speed, and high EMI so it can be used in high-noise environments, such as those found in industrial automation and AV equipment.

The TLP267J(E) is a reliable and robust optoisolator with triac, SCR output for use in a wide range of AC switching circuits from low-voltage domestic appliances up to high-power industrial equipment. Its 5000 VRMS breakdown voltage, low power consumption, and fast switching speeds make it an ideal choice for applications requiring isolation and noise-immunity. The device is also offered in an industry-standard 6-pin DIP package and is compatible with existing industry standards, making it easy to integrate into existing systems.
